## Abstract

A camera module includes a lens imaging system including one or more lenses for imaging incident light on an imaging plane, a filter member disposed between the lens imaging system and the imaging plane, a first protrusion formed on a first surface of the filter member, and a second protrusion formed on a second surface of the filter member.

## Claims

### Claim 1

A camera module, comprising:
a lens imaging system comprising one or more lenses to image incident light on an imaging plane;
a filter member disposed between the lens imaging system and the imaging plane;
a first protrusion formed on a first surface of the filter member; and
a second protrusion formed on a second surface of the filter member,
wherein the first protrusion and the second protrusion comprise different sizes from each other.

### Claim 2 (depends on 1)

The camera module of claim 1, wherein the first protrusion and the second protrusion comprise any one shape of a conical, a truncated conical, a pyramidal, and a truncated pyramidal shape.

### Claim 3 (depends on 1)

The camera module of claim 1, wherein a length of the first protrusion in an optical axis direction is greater than a length of the second protrusion in the optical axis direction.

### Claim 4 (depends on 1)

The camera module of claim 1, wherein the first protrusion and the second protrusion comprise different shapes from each other.

### Claim 5 (depends on 1)

The camera module of claim 1, wherein the first protrusion and the second protrusion comprise different arrangement characteristics from each other.

### Claim 6 (depends on 5)

The camera module of claim 5, wherein the first protrusion is formed at a greater number per predetermined unit of surface area than the second protrusion.

### Claim 7

A portable terminal, comprising:
a terminal body comprising a display panel on one surface thereof;
a camera module disposed in a light transmissive region of the display panel;
a first protrusion disposed on a first surface of the light transmissive region; and
a second protrusion disposed on a second surface of the light transmissive region,
wherein the first protrusion and the second protrusion comprise different sizes from each other.

### Claim 8 (depends on 7)

The portable terminal of claim 7, wherein the first protrusion and the second protrusion comprise different arrangement characteristics from each other.

### Claim 9 (depends on 7)

The portable terminal of claim 7, wherein an area of the light transmissive region is formed to be 1.5 to 2.0 times greater than an area of an incident pupil of the camera module.

### Claim 10 (depends on 9)

The portable terminal of claim 9, wherein the third protrusion and the fourth protrusion comprise different arrangement characteristics from each other.

### Claim 11 (depends on 10)

The portable terminal of claim 10, wherein the first protrusion to the fourth protrusion comprise different arrangement characteristics from each other.

### Claim 12 (depends on 7)

The portable terminal of claim 7, wherein the camera module comprises,
a lens imaging system comprising one or more lenses to image incident light on an imaging plane;
a filter member disposed between the lens imaging system and the imaging plane;
a third protrusion formed on an object-side surface of the filter member; and
a fourth protrusion formed on an image-side surface of the filter member.

### Claim 13 (depends on 12)

The portable terminal of claim 12, wherein the third protrusion and the fourth protrusion comprise different sizes from each other.

### Claim 14 (depends on 13)

The portable terminal of claim 13, wherein the first protrusion to the fourth protrusion comprise different sizes from each other.
